Application filed July 9, 1914. Serial No. 849,993.

and useful Improvement in Clamps, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to clamps designed for clamping ropes or cables, and also for holding brooms or other articles, and an object of the invention is to provide a construction which is of simple form and inexpensive to manufacture.

To this and other ends the invention consists in certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

ln the drawings: Figure 1 shows the clamp in plan attached toa suitable support and vanchoring one end of a rope; Fig. 2 is a side view of the clamp; Fig. 3 shows the clamping member in vertical section;

Fig. 4 is a side elevationof another emi bodiment of the invention; Fig. 5 shows a horizontal section of still another embodiment of the invention; and Fig. 6 is a vertical section of the embodiment shown in Fig. 5.

Referring to the embodiment of the invention shown in Figs. 1 to 3, there is employed a supporting member formed from a single piece of wirel of uniform diameter tit bent to provide a U-shaped portion 1 vwhich has, extending laterally from the end of one arm thereof, a portion 2 formed with screw' threadsl to permit the supporting member to be screwed into a post or other support 3 until the proximate arm of the U-shaped portion abuts the post 3, thereby giving strength to such arm. On Ithe other arm` of the U-shaped portion, a clamping member is journaled and is held thereto by spreading the'arm at- 8.'y This clamping member is preferably in the form of a hollow casting 4 substantially of cylindrical form with a web 5 at the lower part thereof supporting an eccentrically arranged bearing boss 6 which. receives the said arm of the Ll-shaped portion. rThe outer periphery of this clamping member may be formed with parallel longitudinally extending grooves t which are curved in cross section. The purpose of these curved grooves is to prevent the slipping of the rope as the latter is forced by the clamping member against the vopposed arm of the support, it being apparent that the arm substantially conforms to the groove in the clamping member and, in this way, the arm forces the rope into the groove, thereby firmly holding' the rope without any possibility of injury thereto.

In the embodiment shown in Fig. 4, the

support is also made of a single piece ofy wire stock of uniform diameter throughout its length and has an upwardly and laterally-extending arm 9 at one end and a screwthreaded portion 2 at the other end. On the upwardly-extending arm 9, the clamping member 4 is arranged and is the same as shown in Figs. 1y to 3. With this arrangement, the support is not provided with a portion opposed to the clamping member for clamping the rope or the like but, instead, the post or other support 3 serves as the opposed clamping surface, the screw-threaded portion being screwed into the support 3 a distance to provide a suitable `space between the clamping member 4 and the post 3.

In the embodiment of the invention shown in Figs. 5 and 6, the supporting member 1*-1 is of Ufshape and has a clamping member 4 journaled on one arm `thereof as in Figs. 1 to 3. The other arm of the U-shaped member is secured to an attaching plate 10 which is preferably formed from sheet metal and is pressed outwardly at 11 to provide a pocket in which the other arm of the U-shaped support is secured,'being soldered or otherwise secured therein. This outwardly-pressed portion 11 serves as an opposed clamping rib or projection for cooperation with the grooves in the clamping member 4 in the samemanner as the opposed arm of the U-shaped bracket in the construction shown in Figs. 1 to 3.

In the embodiments of the invention illustrated in Figs. 1 to 4, there is provided a supporting member formed from a single piece of stock of uniform diameter having at one end. a screw-threaded portion adapting the support for attachment to a `post or other support while the other end 'has ,a laterally-turned portion serving as a journal for a clamping member. Y

ln the embodiments of the invention shown" in Figs. 1 to 3 and 5 and 6, the sup.- porting member is formed of stock of uniform diameter throughout its length and bent into lll-shape, one arm of the lll-shaped portion Serving as a journal for the clampprising ing member and the other arm carrying means for attaching the device to a post or other support. These embodiments also employ thegrooved clamping member with an opposed transversely-curved jaw so that the 'ropeis clamped between the clamping mem- Without injury thereto by Arate journal for the clamping member, and

when a device .is made from a single piece of stock of uniform diameter throughout its length with a screw formed at one end, the provision of extra fastening devices is made unnecessary.

What I claim as my invention and desire to secure by Letters Patent, is:

1. A clamp of the class described coma clamping member and a support therefor formed from a single piece of wire stock 4and having the clamping member journaled on one end Vthereof and the opposite end formed with screw threads and extending outwardly and laterally with reference to the axis of rotation of the clamping member.

2. A clamp of the class described comprising a clamping member and a support stock, said stock being therefor formed from a single piece of wire stock, said Stock being bent into U-shape and having the clamping member journaled on one arm thereof and attaching means arranged solely on the other arm of the U- shaped portion, the arms having their free ends unconnected and spaced apart to permit a rope or the like to be moved sidewisc between them.

3. A clamp of the class described comprising a clamping member, and a support therefor formed from a single piece of wire bent into U-shape with a screw threaded portion extending laterally from one arm thereof and the clamping member journaled on the other arm.

4:. A clamp of the class described comprising a clamping,r member having .frl periphery provided with parallel longitudinal flutes and a supporting member on which the clamping member is mounted to turn on a fixed pivot, said supporting member having 'a rigid clamping jaw in the form of a single rib curved transversely and of a size to be received within the utes of the movable clamping member.
